Hi Paul, welcome to the forum
I too, wish you best of luck for a wonderfully memorable wedding.
I agree with Arthur, a barong would have to be my top choice as 'groom wear'.
Just relax and enjoy the day, there will be plenty of people to let you know what you must do. No worries.
Best advice, be happy, be polite and just follow.
Try not to ask why this? or why that? You'll just get confused
Importantly, be sure you have and take ALL the required documentations needed.
